  • Patent number: 10807495
    Abstract: According to one embodiment, an electricity storage control device includes a setting unit, and a control unit. The setting unit sets, for each time zone, a target state of charge (SOC) of electric energy to be stored in an electricity storage device in the time zone. The control unit controls at least charging or discharging of the electricity storage device based on the set target SOC for each time zone, a SOC detected from the electricity storage device, and a voltage of a supply destination of electric power from the electricity storage device.
    Type: Grant

  • Publication number: 20170205452
    Abstract: An information processing apparatus of the embodiment includes a calculator. The calculator acquires an amount of primary energy consumption at timings in a period of time and an amount of primary energy production at timings in the period of time. The amount of primary energy consumptions has been consumed and/or is estimated to be consumed by a plurality of energy-supplying apparatuses configured to supply energy to a load. The amount of primary energy productions has been produced and/or is estimated to be produced by the plurality of energy-supplying apparatuses. The calculator calculates a net amount of primary energy consumption at the timings in the period of time, based on the acquired amount of primary energy consumption and the amount of primary energy production. The calculator calculates an integrated value of the net amounts of primary energy consumption over the period of time, based on the net amounts of primary energy consumption calculated at the timings in the period of time.

  • Patent number: 9084198
    Abstract: According to one embodiment, a wireless terminal communicates with a server via wireless base stations. The wireless terminal has devices which transmit a signal in a normal-power transmission mode and the signal in a low-power transmission mode, a power control device which switches the normal-power transmission mode to the low-power transmission mode, or vice versa, and a device which transmits current position data to the server. The server detects the position of the wireless terminal, designates one of the base stations which is close to the wireless terminal, when the wireless terminal is set to the low-power transmission mod, and detects whether the base station designated has a problem or not according to detect the signal from the wireless terminal.

  • Patent number: 5251741
    Abstract: A carrying apparatus having a carrier levitated by a magnetic force. The carrier is movably arranged on the track surface of a track path. A plurality of permanent magnets for generating along the track surface a magnetic field having a predetermined magnetic flux distribution pattern in a direction perpendicular to the extending direction of the track path are provided on the track path. A superconductor element is mounted in the carrier. The superconductor element traps (pins) the magnetic flux of the magnetic field which is applied during transition from the normal conducting state to the superconducting state. The superconductor element supplies a levitating force and a guide force acting in a direction perpendicular to the extending direction of the track path to the carrier by the magnetic force generated between the trapped magnetic flux and the magnetic field generated by the permanent magnets on the track path.
